Do you have any idea how much work must be done to make a competition like this to happen? Reserve rooms, install computers, buy some food, print certificates - these are only some of the important tasks. Can you imagine how many sleepless nights have been spent since the first CTU competition in 1995? And this was only for people like you to enjoy the ICPC. Wow!
Beside others, the problem set must be carefully prepared. This includes not only the problem statements but also solutions and test data. It is really a large amount of work. Would you help us, please? Your task is to create a test input data for the Problem B (banking).
